Really exciting video! One way to extend the campaigns would be to make use of some the extra map space the originals didn't use such as Scotland and Inner France with Characters they didn't add in Vanilla I.e Mokuba for Kaiba, Duke Devlin for Yugi and so on.

That is exactly why I started architecting the "campaign maps" system the way I did. Essentially campaign maps are going to have the ability to be represented with packs and eventually, custom campaign packs will be a thing. By the time the remake is "done" I'd like to include the two standard campaigns (red rose/white rose) and then an expanded campaign of sorts.
